In Norway 5.8% of students report being bullied as much as three or more times a month [UDIR. 2021a. Student Survey 2020 [Elevundersøkelsen 2020]. https://www.udir.no/tall-og-forskning/finn-forskning/rapporter/elevundersokelsen-2020-nasjonale-tall-formobbing-og-arbeidsro/]. The present study investigates the likelihood of students being bullied…

Employing a statistical modeling inspired pedagogy is becoming a widespread practice in the statistics education community. Many have incorporated the practice of formulating conjectures in their modeling-enhanced educational designs and have reported on its benefits. We further elucidate the mechanism through which students' conjecturing may be…

This paper investigates two specific probabilistic biases which middle graders usually exhibit when reasoning about probability and randomness on assessment items. We discuss how students' reasoning about key probability concepts undergirds statistics literacy related to randomness, independence, and the likelihood of future events based on past…

This direct replication study compared the use of dichotomized likelihood ratios and interval likelihood ratios, derived using a prior sample of students, for predicting math risk in middle school. Data from the prior year state test and the Measures of Academic Progress were analyzed to evaluate differences in the efficiency and diagnostic…

Equal representation as a social issue is about the participation of one social group, in a particular context, in proportion to the numbers in the group within the total population. The proportion of women in parliament, and of the participation rate of students of lower socioeconomic status in higher education, are examples. The aims of this…

Reform movements in mathematics education advocate that mathematical argumentation play a central role in all classrooms. However, research shows that mathematics teachers at all grade level find it challenging to support argumentation in mathematics classrooms. This study examines the role of teachers' mathematical knowledge in teachers' support…

The frequentist and classical models of probability provide students with different lenses through which they can view probability. Prior research showed that students may bridge these two lenses through instructional designs that begin with a clear connection between the two, such as coin tossing. Considering that this connection is not always…

Middle school is an important crossroad in a student's academic journey. As students enter middle school, their academic achievement and engagement frequently declines. This is true particularly for Black and Latinx students. Poor middle school grades are often a harbinger of poor performance in high school and beyond. In particular, having a…

The "Academic Mindsets and Behaviors, Prior Achievement, and the Transition to Middle School" study examined the relationship between 2016/17 grade 5 student responses to a Clark County School District (Nevada) survey on levels of academic mindsets and behaviors and the predicted probability of earning a low GPA (below 2.0) at the end of…

Few studies have been conducted to investigate typologies of perpetration and victimization of traditional and cyber bullying together to develop a risk profile by considering factors from different contexts. National data from the 2009-2010 Health Behavior in School-Aged Children study in the United States was utilized for these purposes. Four…

The research shared in this conference paper report illustrates how an iterative process to item development that involves expert review and cognitive lab interviews with students can be used to collect evidence of validity for assessment items. Analysis of students' reasoning was also used to expand a model for identifying conceptions and…

The present study examined how school-age children's communicative decisions are influenced by the situation, their social partner, and their own characteristics (gender, shyness levels, and history of peer relationships). Children (8-12 years old, N=246) imagined themselves in social scenarios (depicted through comics) and indicated the…

This report is based on an activity completed by 89 Grade 6 students carrying out a statistical investigation with a focus on posing an initial question given a context and then refining it for a chosen data set. Having reached a conclusion based on evidence from their data analysis, students were given additional information on the context and…

Curriculum Associates' i-Ready is an adaptive diagnostic and individualized instructional tool that has been used in M-DCPS in the last few years. In addition, Curriculum Associates provides the District with results of their predictive model, which uses the students' outcomes on the Fall and Winter i-Ready diagnostic testing as well as the…

Background: Like adults, children need to allocate study time and endeavour optimally in order to enhance learning effectiveness. Aims: The aim of this study was to investigate the development of shifting from habitual to agenda-based processes on study decisions. Sample: The participants were 309 children in the second, fourth, and sixth grades.…
